Why is it important to know the value of the voltage in the battery

Thanks to an ordinary battery, such a small element, we use various devices without connecting them to the network. We can safely say that the discovery that led to the emergence of this power source, in some way, turned our world upside down. However, when using this product, do not forget about its one very important characteristic - voltage or, in other words, power.

What is battery voltage

Many people know that lithium batteries have a voltage of 3 volts, and alkaline and alkaline ones are 1.5. But what do these numbers mean? They show the current that is generated by one link in the electrical circuit. As we understand it, such a low rate does not cause any harm to our health, as well as to the device itself. If you need to get an increased voltage, then you need to connect several elements in a circuit, i.e. combine them into one whole.

It is interesting! For example, to obtain 6 V, it is necessary to successively add 4 such batteries into a single circuit.

It is worth noting that some users use the term "power" instead of the concept of voltage. Although, in fact, there is no such thing. This criterion may vary depending on the type of power source, as well as the chemical elements that make up it.

Why is it important to know the value of the voltage in the battery

As you can understand, it is the voltage that is the most important technical characteristic of this battery.It shows how long the battery will last, as well as how much it fits with a particular device.

It is worth considering the option that the battery begins to lose its power after a while. If the voltage drops, then the device starts to work incorrectly or does not work at all. If the voltage is higher, for example, 3.2 V (lithium-ion), then such batteries will simply damage the device, which is designed for a lower voltage. Therefore, it is simply impossible to ignore the "voltage" when buying this product.

It is interesting! Many people wonder why 1.2 volts is written on AA batteries, and whether it is enough for the normal functioning of the device, if 1.5 is almost always written on them. The fact is that 1.2 V is an EMF (electromotive force) of a specific electrochemical pair - for this reason, these numbers are indicated on the case. The real voltage indicator in this case is almost always 1.5-1.55 V (provided that the product is new, of high quality or fully charged).

How many volts are in penlight and other types of batteries

As we said, the voltage in a battery depends on two main factors:

• battery type;
• its composition.

For example, in finger (size AA) it is 1.5. If we talk about nickel-zinc elements, then here it will be about 1.6 V, for nickel-cadmium and nickel-metal hydride less than 1.4. However, there are also lithium-ion and lithium-iron-phosphate batteries, in which the voltage is as much as 3.2 Volts. The problem is that such batteries can damage devices that are rated for 1.2-1.5 V.

The "pills" have about the same voltage as the AA: from 1.4 to 3 V. Voltage also depends on size and composition (highest for lithium CPs, lowest for zinc-air PRs).

For galvanic batteries with AAA standard size, the "voltage" is from 1.2 to 3.7 V.

As we can see, when buying a regular battery it is not enough to tell the seller that you “need a battery”. In order for it to fit and be useful, you need to know its size and voltage.
